A characterization of the data, including its intended use and limitations.

Abstract:

In order for the state of Idaho to utilize temperature criteria to protect various stream uses, such as spawning, the state is required to designate when and where spawning may occur. While Idaho previously has some waters designated for salmonid spawning in its water quality standards, many other waters where salmonids may or do spawn remain undesignated. This data takes the Idaho 305(b) streams and determines which portions of them are possible salmonid spawning areas.

Purpose:

These data were generated using the Idaho 305(b) streams layer and plotting the StreamNet salmonid spawning run location data along those streams. In addition, based on best available documentation and a number of agency contributions of professional judgment and known surveying, these areas were attributed at the HUC12 level with known salmonid spawning and emergence dates down to the nearest week.

Metadata Standards

Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.

Standard name: FGDC Content Standard for Digital Geospatial Metadata

Standard version: FGDC-STD-001-1998

Time convention: local time

FGDC Plus Metadata Stylesheet

Stylesheet: FGDC Plus Stylesheet

File name: FGDC Plus.xsl

Version: 2.0

Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well.
The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
